Is there a difference between the GMPP Super Magnum T56 and the T56 (TUET11009) which most of the aftermarket transmission vendors sell? I talked to a GM performance dealer about pricing and they said their cost was several hundred dollars higher than the going rate for the aftermarket T56 Magnums.
Super mag has a 40 tooth reluctor so the ecu can read speed. That is literally the only thing. Now if your smart the best way is to buy the cheaper one, get your engine tuned and while he’s at it change the speedometer info and bam you have the same thing.

The description in camaros.net also worked perfectly for me: LSA w/ Tremec Magnum, 3.60 rear. Leave the VSS pulses at 40, multiply the actual rear gear ratio by 12/40 and enter that value, which came out to 1.08 for me, in the Final Drive, Speedo tab in HP Tuners VCM Editor. I'd be scared to drive my car without the reverse lockout function working correctly!
